response.

They draw 180ma whether on or off. When driven with 3 watts AM into a
50 ohm dummy load, it draws 500ma (whether on or off) but has no RF
output.

An SWR meter shows very high SWR between the radio and the amp.

With the amp out of the circuit, I see 1.0 SWR and 3 watts on the
meter.

With power to the amp off, and 3 watts AM in, there is no RF out.

Three KL40's I've tested are doing the same thing.

Is it possible they switched the wiring to the PL-259's for a big run
of these?

Anyone seen this problem with KL40's?

Problem is solved. These are for export and need to be "converted" to
work with American electrons. ;-)

Just make sure you get a competent tech to perform the marriage
ceremony correctly between the radio and amp, not one who impersonates a
tech and claims you should probably replace c-1 in all three brand new
amps.

Better yet, find a tech who understands that "There are a lot of possible
scenarios for what he is describing".

Like a tech who believes three brand new amps have shorts in C1?

You'd do a better job in enhancing your worth to this group if you'd
post with a little more manners, use common sense, and also know when
not to post?

Did I say I believe they all had bad caps? No. I said it was -possible-, and it
is. Better read more carefully or TwistyDave is going to start whining about
your communication deficits.

But I -do- know when not to post -- I don't post when I don't know what I'm
talking about, like issues regarding many popular radios such as Ranger, RCI,
etc. I don't know anything about those except that most are easily modified to
operate illegally. I couldn't tell you anything beyond that. What I -do- know is
how to read a schematic, how to analyze a bad circuit, and how to locate
possible causes of failure. And I -do- know how an RF amplifier works, as well
as the operational characteristics of each and every component, active and
passive. I -also- know that manufacturing processes can sometimes turn loose an
entire lot of bad products, whether they are the final products or their
components. And yes, I -also- know that sometimes there are unknown faults in
equipment that can cause failures in other equipment. And I -=ALSO=- know that
some people will keep replacing fuses as fast as they blow them without even
thinking that the fault is not the fuse. In other words, it is not uncommon for
someone to test two or more brand new products, discover that they are broken,
and not realize that they were rendered non-functional as a result of their own
bad test equipment or procedure. This happens quite frequently when the products
have very static sensitive components (such as MOSFET's). You have therefore
demonstrated that you have very little, if any, experience working with such
devices, and should probably take your own advice (learn when not to post).

First time responding on here but I've been having an issue with high swrs on my kl 60 which I believe to be very similar to the kl 40. I have tested the swr in multiple ways in the system, with amp and without. To give a rundown of my setup I have 9ft of coax running from radio to amp because the radio is mounted on the ceiling console however you want to call it. I have the amp on the floor then I have the coax running out to the antenna which for that antenna I'm wanting to say 17ft but I'm not sure what the antenna came with. The antenna is a tram 300. So without the amp being there and putting a meter there instead to check swrs, and with a meter at the back of the radio everything seems within reason swr wise. I'm getting between a 1.4 to 1.6 on 1 and 40 which I'm not complaining though when it rains it starts to climb on 40. My main issue is when taking a reading with the amp there but not on, taking it from the radio side or antenna side it reads a 2 to 1 on 40. I suspect that the amp is the problem because everything checks out without it. Now get this, with the amp on, on the antenna side it drops back down to 1.6. So it's only high with amp being there and off unless I max radio power to amp when on then itll show 2 to 1 again. Anything below 3 or 4 watts deadkey its fine. So someone explain to me what inside an amp would give for a high swr when off, thanks.
